significant given the volume, 120 of them, a fact that many were quite shiny and so on. what did you read into the details that you've seen? >> what i read into thesis if again -- this is all if they can find an item that these are the plane. so assuming they are wreckage from flight 370, these satellite images just became our biggest clues. because we have multiple images from multiple days from multiple countries. if the resolution that they have can be shared, even if it's not public knowledge and we can identify them as the exact same pieces, we now have data to plug into a drift model to follow it back. >> what people say to me is, if there's all these satellite images everywhere, from the chinese, the australians, the french now, why can't we just go and get them? what is the explanation for that? >> it's a big ocean and they're moving parts, 30, 40-foot seas and wind. they get out there and find them with a plane and send a boat out and it takes two day to get there. then they move and it's rough and they have to run and hide from a hurricane.
